Introduction
Whole genome sequencing (WGS) involves a set of laboratory methods used to determine the full genome
sequence of an organism or virus, which in the case of Severe Acute Respiratory Syndrome Coronavirus 2
(SARS-CoV-2), the virus that causes Coronavirus Disease 2019 (COVID-19), is approximately 30,000 letters,
each letter being one of A, C, G, or T.
The genome sequence of a virus can reveal mutations that make it unique. Mutations are changes in a genome
sequence (usually one-letter changes) and occur naturally over time.
Collecting the genome sequences of virus specimens can reveal information about the relatedness of viruses
and the similarities shared among groups of viruses. Groups of same-species viruses that share a set of
genome mutations are referred to as a lineage.
Scientists compare viral genomes to better understand virus transmission, how viruses can spread from
person to person. Sequencing also allows Public Health Officials to monitor viruses involved in outbreaks,
characterize outbreaks, detect clusters of cases, and monitor new lineages. Novel mutations can emerge with
new lineages and scientists refer to these new lineages as emerging variants.
Some of these variants are classified by the Centers for Disease Control and Prevention (CDC) as variants
of concern and others as variants being monitored, because of their attributes, which, for example, can
be increased transmissibility, decreased neutralization by antibodies generated during previous infection or
vaccination, or increased severity of disease. The CDC has extensive information about SARS-CoV-2 variant
classification (https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/variant-surveillance/variant-in
fo.html), which is updated as new evidence becomes available.
Sequencing can only be performed on samples that contain SARS-CoV-2 RNA, which means only samples
used for molecular tests (such as PCR) can be included. Therefore, this report is limited to confirmed
PCR-positives only. The genomes that are sequenced and compared are those of the virus, not humans.
Sequencing can be performed on stored specimens at any time. Therefore, the dataset used for this report is
dynamic and batches of stored specimens that are newly sequenced will be added to the dataset as sequencing
occurs. Because of this, trends based on historical data can change over time.
The State of Hawaii has conducted sequencing on approximately 5% of positive specimens since testing began,
according to the CDC (https://covid.cdc.gov/covid-data-tracker/#published-sars-cov-2-sequences).
In February 2021, State Laboratories Division, Hawaii Department of Health increased sequencing efforts
done on positive samples to improve the State’s ability to detect new variants of concern and variants being
monitored.

Summary and key notes
 • State Laboratories Division has reported an additional 344 sequenced SARS-CoV-2 genomes since the
   previous variant report was generated (1/14/2022).
 • The CDC and its commercial partners have reported an additional 139 sequenced SARS-CoV-2 genomes
   from the State of Hawaii since the previous variant report was generated (1/14/2022).
 • TAMC has reported 1 additional sequenced SARS-CoV-2 genome from the State of Hawaii since the
   previous variant report was generated (1/14/2022).
 • SARS-CoV-2 variant nomenclature is defined by a World Health Organization (WHO) label (letters of
   the Greek Alphabet, i.e., Alpha, Beta, Gamma, Delta, etc.), Pango lineage (alphabetical prefix and a
   numerical suffix), and/or Nextstrain clade (year of emergence followed by a letter ordered alphabetically
   by emergence, i.e., 20A, 20B, etc.). In this report, variant counts are reported using the WHO label
   and Pango lineage (or “Lineage”) nomenclatures only.
 • Classifications of Delta lineages are in flux. Since the previous report, a significant proportion of Delta
   genomes previously classified as parent lineage B.1.617.2 have been reclassified as an AY.* sub-lineage.
   Furthermore, for simplicity, not all AY.* sub-lineages identified in the State of Hawaii or its counties are
   outlined in the Tables on the following pages, and instead are included as “Other AY.*” under Lineage.
 • Classifications of Omicron lineages are in flux. Since the previous report, a significant proportion of
   Omicron genomes previously classified as sub-lineage BA.1 have been reclassified as sub-lineage BA.1.1.
   With this reclassification, BA.1.1 has been more prevalent than BA.1 in the State of Hawaii since the
   Omicron wave began; however, the comparative proportions of BA.1 and BA.1.1 among total Omicron
   detected in the State have remained steady since Omicron became the dominant variant.
 • The Omicron sub-lineage BA.2, which was first detected in South Africa in late November 2021 and
   subsequently classified in early December 2021, has recently been detected in the State of Hawaii. BA.2
   has reportedly outpaced BA.1 and BA.1.1 to become the dominant Omicron variant in some countries,
   and thus is suspected of being more infectious than BA.1 and BA.1.1. However, there are no scientific
   data published to date to indicate whether transmissibility differs between Omicron lineages.

Significance of variants of concern and variants being monitored
It is important to note that evidence to date shows that vaccination leads to milder cases, not requiring
hospitalization, for all variants of concern and variants being monitored that are described here, even if the
efficacy of antibodies is diminished against some of these variants compared to the original version of the
virus.
Also, none of these variants are classified as a “variant of high consequence”, according to CDC variant
categories (https://www.cdc.gov/coronavirus/2019-ncov/variants/variant-info.html#Consequence), which is
a category that would imply a variant has the ability to evade diagnosis, significantly reduce the vaccines
effectiveness and protection against severe disease, significantly reduce susceptibility to treatments, or lead to
more severe disease and increased hospitalizations.

Variants of concern (VOC)

Delta variant (B.1.617.2 and AY.* sub-lineages)

B.1.617.2 was first identified in India and the WHO labeled it “Delta” on May 31, 2021. This variant contains
the L452R mutation in the spike protein, which has been shown to escape neutralization by monoclonal
antibodies and some convalescent sera, as well as a few additional spike mutations predicted to have functional
consequences (e.g. T478K). The Delta variant is highly contagious, more than 2x as contagious as previous
variants. The Delta variant is also known as Nextstrain clade 21A, 21I, and 21J. For more information about
Delta, go to (https://www.cdc.gov/coronavirus/2019-ncov/variants/delta-variant.html).

Omicron variant (B.1.1.529 and BA.* sub-lineages)

B.1.1.529 was reported to the WHO on November 24, 2021 and first detected in specimens collected on
November 11, 2021 in Botswana and on November 14, 2021 in South Africa. The WHO named the B.1.1.529
“Omicron” and classified it as a VOC on November 26, 2021. The United States designated Omicron
as a VOC on November 30, 2021 and reported its first case on December 1, 2021. Omicron contains
more changes in the spike protein than have been observed in other variants, including at least 30 amino
acid substitutions (15 of these are in the receptor binding domain), three small deletions, and one small
insertion. Several of these mutations, including S477N, N501Y, and E484K, have been associated with
increased infectivity and decreased neutralizing activity of monoclonal antibodies and convalescent sera.
Evidence suggests that Omicron is more transmissible and more immune evasive than previous variants,
and that immunity conferred by prior infection or vaccination may be reduced compared to Delta; however,
the clinical severity of Omicron infection compared to previous variants remains unclear. The Omicron
variant is also known as Nextstrain clade 21M, 21K, and 21L. For more information about Omicron, go to

Variants being monitored (VBM)

Alpha variant (B.1.1.7 and Q.* sub-lineages)

B.1.1.7 was first identified in the United Kingdom and the WHO labeled it “Alpha” on May 31, 2021. This
variant contains the N501Y mutation and a short deletion in the spike protein. This variant is concerning
because it has been shown to be significantly more transmissible (~50%) than the original SARS-CoV-2 lineages
and reports from the United Kingdom suggest that B.1.1.7 cases are more likely to require hospitalization.
B.1.1.7 does not appear to evade vaccine-induced neutralizing antibody responses. The Alpha variant is also
known as Nextstrain clade 20I.

                                                        6
Gamma variant (P.1 and P.1.* sub-lineages)

P.1 was first identified in Brazil and the WHO labeled it “Gamma” on May 31, 2021. This variant also
contains the N501Y mutation, like B.1.1.7, but not the deletion in the spike protein. Preliminary studies
suggest that antibodies from previous infection or from vaccination may be less effective at preventing
infection against this variant. The Gamma variant is also known as Nextstrain clade 20J.

Beta variant (B.1.351 and B.1.351.* sub-lineages)

B.1.351 was first identified in South Africa and the WHO labeled it “Beta” on May 31, 2021. This variant is
highly infectious and can quickly spread from person to person. Preliminary studies suggest that antibodies
from previous infection or from vaccination may be less effective at preventing infection against this variant
due to presence of the E484K mutation in the spike protein. The Beta variant is also known as Nextstrain
clade 20H.

Mu variant (B.1.621 and B.1.621.1)

Lineage B.1.621 was first identified in Columbia in January 2021 and it has a couple of mutations in common
with the Beta (B.1.351) and Gamma (P.1) variants, which have been associated with high transmissibility
(N501Y) and a level of decreased vaccine efficiency (E484K). The MU variant is also known as Nextstrain
clade 21H.

Iota variant (B.1.526)

B.1.526 was first identified in New York and is classified by CDC as a VBM because of indications that it has
increased transmissibility. The WHO labeled it “Iota” on May 31, 2021. Some of the samples (but not all) of
this variant contain the E484K mutation. The Iota variant is also known as Nextstrain clade 21F.

Epsilon variant (B.1.429 and B.1.427)

The closely related lineages, B.1.429 and B.1.427, were first identified in California and designated initially as
CA VUI1. The WHO labeled them “Epsilon” on May 31, 2021. They can quickly spread from person-to-
person, with an estimated ~20% higher efficiency than the original virus. The CDC has deescalated Epsilon
from a VOC to VBM on June 29, 2021, due to the significant decrease in the proportion of B.1.429/B.1.427
lineage viruses circulating nationally, as well as the available data indicating that vaccines and treatments are
effective against this variant. CDC removed B.1.429 and B.1.427 from the VBM list in July 2021 due to
declining prevalence. The Epsilon variant is also known as Nextstrain clade 21C.

Figure Notes:
       • The graph shows the total number of variants by lineage detected in the State of Hawaii in each 2-week
         interval ending on the date shown (date represents when the specimen was collected from a patient).
       • Variants of concern shown are Delta (lineages B.1.617.2 + AY.*) and Omicron (lineages B.1.1.529 +
         BA.*).
       • Variants being monitored shown are Alpha (lineages B.1.1.7 + Q.*), Beta (lineage B.1.351), and Mu
         (lineages B.1.621 + B.1.621.1).
       • The gray bar graph (top) shows the percentage of PCR-positive samples from each 2-week time interval
         that were sequenced.
       • SARS-CoV-2 genome sequencing may not be a random sample of all cases. This graph does not estimate
         prevalence in the population.
       • Sequencing can be performed on stored patient specimens at any time, so these numbers may change as
         additional specimens are sequenced.

Figure Notes:
                               • The graph shows biweekly percentage estimates of SARS-CoV-2 variants circulating in the State of
                                 Hawaii, grouped in two-week intervals (based on the date of sample collection).
                               • Not all positive SARS-CoV-2 specimens are sequenced and sequenced specimens are not a random
                                 selection of all COVID-19 cases in the State of Hawaii. This graph has been generated only counting
                                 samples that were selected randomly for the purpose of surveillance, to avoid over-representing the
                                 samples that were selected for investigations of clusters.
                               • The last 2-week interval numbers will most likely change, as a number of samples that are currently
                                 being processed will be added.
                               • Sequencing of certain specimens can be delayed for technical reasons. Therefore, the dataset used
                                 for this report is dynamic and specimens that are newly sequenced will be added to the dataset as
                                 sequencing occurs. Because of this, trends based on historical data can change over time.

                                                                                                                                              9

         ending on the date shown (date represents when the specimen was collected from a patient).
       • Variants of concern shown are Delta (lineages B.1.617.2 + AY.*) and Omicron (lineages B.1.1.529 +
         BA.*).
       • Variants being monitored shown are Alpha (lineages B.1.1.7 + Q.*), Beta (lineage B.1.351), and Mu
         (lineages B.1.621 + B.1.621.1).
       • The gray bar graph (top) shows the percentage of PCR-positive samples from each 2-week time interval
         that were sequenced.
       • SARS-CoV-2 genome sequencing may not be a random sample of all cases. This graph does not estimate
         prevalence in the population.
       • Sequencing can be performed on stored patient specimens at any time, so these numbers may change as
         additional specimens are sequenced.

Figure Notes:
                               • The graph shows biweekly percentage estimates of SARS-CoV-2 variants circulating in Honolulu County,
                                 grouped in two-week intervals (based on the date of sample collection).
                               • Not all positive SARS-CoV-2 specimens are sequenced and sequenced specimens are not a random
                                 selection of all COVID-19 cases in Honolulu County. This graph has been generated only counting
                                 samples that were selected randomly for the purpose of surveillance of community variants, to avoid
                                 over-representing the samples that were selected for investigations of clusters.
                               • Sequencing of certain specimens can be delayed for technical reasons. Therefore, the dataset used
                                 for this report is dynamic and specimens that are newly sequenced will be added to the dataset as
                                 sequencing occurs. Because of this, trends based on historical data can change over time.

                                                                                                                                         13

Figure Notes:
     • The graph shows the total number of variants detected in Maui County in each 2-week interval ending
       on the date shown (date represents when the specimen was collected from a patient).
     • Variants of concern shown are Delta (lineages B.1.617.2 + AY.*) and Omicron (lineages B.1.1.529 +
       BA.*).
     • None of the variants being monitored were detected during the time periods shown.
     • The gray bar graph (top) shows the percentage of PCR-positive samples from each 2-week time interval
       that were sequenced.
     • SARS-CoV-2 genome sequencing may not be a random sample of all cases. This graph does not estimate
       prevalence in the population.
     • Sequencing can be performed on stored patient specimens at any time, so these numbers may change as
       additional specimens are sequenced.

Figure Notes:
                               • The graph shows biweekly percentage estimates of SARS-CoV-2 variants circulating in Maui County,
                                 grouped in two-week intervals (based on the date of sample collection).
                               • Not all positive SARS-CoV-2 specimens are sequenced and sequenced specimens are not a random
                                 selection of all COVID-19 cases in Maui County. This graph has been generated only counting
                                 samples that were selected randomly for the purpose of surveillance of community variants, to avoid
                                 over-representing the samples that were selected for investigations of clusters.
                               • Sequencing of certain specimens can be delayed for technical reasons. Therefore, the dataset used
                                 for this report is dynamic and specimens that are newly sequenced will be added to the dataset as
                                 sequencing occurs. Because of this, trends based on historical data can change over time.

                                                                                                                                        17

Figure Notes:
       • The graph shows the total number of variants detected in Hawaii County in each 2-week interval ending
         on the date shown (date represents when the specimen was collected from a patient).
       • Variants of concern shown are Delta (lineages B.1.617.2 + AY.*) and Omicron (lineages B.1.1.529 +
         BA.*).
       • Variants being monitored shown are Alpha (lineages B.1.1.7 + Q.*).
       • The gray bar graph (top) shows the percentage of PCR-positive samples from each 2-week time interval
         that were sequenced.
       • SARS-CoV-2 genome sequencing may not be a random sample of all cases. This graph does not estimate
         prevalence in the population.
       • Sequencing can be performed on stored patient specimens at any time, so these numbers may change as
         additional specimens are sequenced.

                                 samples that were selected randomly for the purpose of surveillance of community variants, to avoid
                                 over-representing the samples that were selected for investigations of clusters.
                               • Sequencing of certain specimens can be delayed for technical reasons. Therefore, the dataset used
                                 for this report is dynamic and specimens that are newly sequenced will be added to the dataset as
                                 sequencing occurs. Because of this, trends based on historical data can change over time.

Figure Notes:
       • The graph shows the total number of variants detected in Kauai County in each 2-week interval ending
         on the date shown (date represents when the specimen was collected from a patient).
       • Variants of concern shown are Delta (lineages B.1.617.2 + AY.*) and Omicron (lineages B.1.1.529 +
         BA.*).
       • None of the variants being monitored were detected during the time periods shown.
       • The gray bar graph (top) shows the percentage of PCR-positive samples from each 2-week time interval
         that were sequenced.
       • SARS-CoV-2 genome sequencing may not be a random sample of all cases. This graph does not estimate
         prevalence in the population.
       • Sequencing can be performed on stored patient specimens at any time, so these numbers may change as
         additional specimens are sequenced.

Figure Notes:
                               • The graph shows biweekly percentage estimates of SARS-CoV-2 variants circulating in Kauai County,
                                 grouped in two-week intervals (based on the date of sample collection).
                               • Not all positive SARS-CoV-2 specimens are sequenced and sequenced specimens are not a random
                                 selection of all COVID-19 cases in Kauai County. This graph has been generated only counting
                                 samples that were selected randomly for the purpose of surveillance of community variants, to avoid
                                 over-representing the samples that were selected for investigations of clusters.
                               • Sequencing of certain specimens can be delayed for technical reasons. Therefore, the dataset used
                                 for this report is dynamic and specimens that are newly sequenced will be added to the dataset as
                                 sequencing occurs. Because of this, trends based on historical data can change over time.
